What device should I use as a start point in autoMap discovery ?
Why must it be SNMP compliant The Start Point for autoMap is the Seed address for the discovery process, it should be the IP address of an SNMP device that is to be used as the origin of the discovery. If possible, a central router should be used. Virtual IP addresses used by HSRP or VRRP should be avoided, i.e., device must be SNMP-capable and have one of its physical interfaces configured to support SNMP. A single address point of an SNMP Router is recommended, but you can have multiple start points, the format to used to configure multiple start points = 192.168.0.1,10.0.1.1-10.0.1.254 The discovery process will involve inspecting the ARP and forwarding tables (if present) for the seed-device to see who is communicating with whom and then start to interrogate those devices. As it finds the next switch or router it starts to see more devices and the discovery process works in a recursive manner until it sees all active devices. As ARP and forwarding tables get flushed after 5 minutes
